c# - update list of objects from another list-CodePudding

I have a list of object.

"result": [
    {
        "primaryKey": "123",
        "count": 0,
        "details": [
            {
                "employeeName": "Chris",
            }
        ],
    },
    {
        "primaryKey": "456",
        "count": 10,
        "details": [
            {
                "employeeName": "Nick",
            }
        ],
    },
]

And another list.

"result": [
    {
        "foreignKey": "123",
        "details": [
            {
                "employeeName": "Sean",
            }
        ],
    },
    {
        "foreignKey": "789",
        "details": [
            {
                "employeeName": "Andrew",
            }
        ],
    },
]

I want to update the details property of the first list with the contents of second list details, if the primary key and foreign key matches.

CodePudding user response：

foreach(obj item in result1)
{
    if(result2.where(x => foreignKey == item.primaryKey).Any())
    {
       string EmpName = result2.where(x => foreignKey == item.primaryKey).FirstOrDefault().employeeName;
       item.employeeName = EmpName ;
    }
}
